What are the types of coal?

What are the types of coal? There are four major types (or "ranks") of coal. Rank refers to steps in a slow, natural process called "coalifiion," during which buried plant matter changes into an ever denser, drier, more carbonrich, and harder material. The four ranks are: Anthracite: The highest rank of coal.
